‘d’ is meant by ‘a small change’ in the quantity. It can also be represented by \Delta(Delta) for a larger change in quantity

dm/dt is used in situations with variable mass. for example: when a rocket goes up, it consumes its fuel and hence looses mass or there is a chnge in mass (from the initial mass)...When mass is variable,  F(force)=d(mv)/dt.  This can be also written as  F= m.(dv/dt) + v.(dm/dt).
